IMPROVEMENT IN ARTIFICIAL TEETH.

Specification forming part of Letters Patent No. 36,234, dated August 19, 1862.

To all whom, it may concern.-

Beit known that we, DAVID POLLOOK and JOHN POLLOcK, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a newr and improved mode of making and rendering more useful the base and gums of articial teeth, thereby rendering them less liablev to be broken; and we do hereby declare that the following is a full, clear, and exact description Of the same, reference being had to the accompanying drawings, forming a part ofthis speciiication, in whiche Figure 1 is a longitudinal section of the upper jaw; Fig. 2,a longitudinal section of lower jaw. Fig. 31's a partial upper plate; Fig. 4., a full upper plate. Fig. 5 is a full under plate. Fig. 6 is a partial under plate; Fig. 7, a perspective'view of partial upper plate; Fig. 8, a longitudinal section of partial upper plate; Fig. 9,'a longitudinal section of partial lower plate; Fig. 10, metallic wires or strips; Fig. 11,a perspective view of full upper plate; Fig. 12,a perspective view of full under plate; Fig. 13, a perspective view of partial underplate.

The nature Of our invention consists in the use of metallic strips or wires composed of platina or other suitable metal, and embedding or molding the same in the plate, gums, Or base of porcelain or any other substance used in the manufacture of artificial teeth, thereby rendering them stronger and more useful. y

To enable Others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

The base and teeth are formed in the ordi nary manner of making porcelain plate-teeth while the composition is in a soft and pliable state, yand before crusng or heating we insert or mold in the plate, gums, Or base wire Or strips composed of platina Or other suitable metal, after which the whole is finished in the usual manner,said strips or wires to be placed transverse, longitudinal, Or in any other Way or form, as shown in all the drawings and ligures marked A, and which can easily be seen in the models by holding them up to the light,or in any way, manner, or form that will best answer the purpose, said wires or strips can beinserted after crusing and before enameling; but' we prefer putting them in` before crusing and about the time of carving the teeth.

Fig. 10, letter A, are strips `or wires com` posed of platina or other suitable metal for inserting in the base or plate, of porcelain or other teeth,and are to be of such length,shape, and size as shall be found necessary for the purpose intended.

We wish it to be distinctly understood that we believe ourselves to be the rstinventors of the mode of making artieial teeth, combining wire or slipsof metal With porcelain or any other substance,thereby making the plate or base of artificial teeth much stronger and more useful. v

Ve do not claim the manufacture of porcelain artificial teeth; but

.Vhat We do claim, and wish to secure by Letters Patent, isy 1. The use of metallic strips or Wires composed Of platina Or other suitable metal to be used longitudinally, transversely, Or crossing each other like net-work inserted or molded in the plate, gums, and base of artificial teeth composed of porcelain or other substance,sub-

stantially as set forth in this speciiicatiomand as will best answer the purpose intended.

2. The use of metallic strips Or wires composed Of platina or other metal to be used iu sectional parts of artificial teeth, and also in the teeth, substantially as set forth, and for the purpose intended.
